| 中文摘要: |
| 介绍445/45R19.5宽基无内胎全钢载重子午线轮胎的设计。结构设计：外直径 896.5 mm,断面宽 448 mm，行驶面宽度 400 mm,行驶面弧度高 15.5 mm,胎圈着合直径 493.5 mm,胎圈着合宽度 394 mm,断面水平轴位置(H1/H2) 0.87，采用以6条纵向花纹沟为主的胎面花纹，花纹饱和度 79.75%，花纹深度 13 mm，花纹周节数 32。施工设计：胎面采用三方四块结构，2#和3#带束层采用3＋8×0.33HT钢丝帘线，1#和4#带束层采用3×0.206×0.35HT钢丝帘线，胎体采用1＋6＋12×225HT钢丝帘线,采用两鼓成型机成型、热板式双模硫化机硫化。成品轮胎性能试验结果表明，轮胎的充气外缘尺寸符合设计要求，强度性能、耐久性能、速度性能和滚动阻力均达到相应标准要求。 |
| 英文摘要: |
| The design of 445/45R19.5 wide base tubeless truck and bus radial tire was described.In the structure design,the following parameters were taken:overall diameter 896.5 mm,cros-sectional width 448 mm,width of running surface 400 mm,arc height of running surface 15.5 mm,bead diameter at rim seat 493.5 mm,bead width at rim seat 394 mm,maximum width position of cross section(H1/H2) 0.87,tread patterns mainly composed of six longitudinal grooves，block/total ratio 79.75%，pattern depth 13 mm,and pattern circular pitch 32.In the construction design,the following processes were taken:three-formula and four-piece tread structure,3＋8×0.33HT steel cord for 2# and 3# belt，3×0.20＋6×0.35HT steel cord for 1# and 4# belt，1＋6＋12×225HT steel cord for carcass ply，and using two-drum building machine to build tires and hot press to cure tires.It was confirmed by the test of finished tires that，the inflated peripheral dimension met the requirements in the design,and the strength performance,enduranceperformance,speed performance and rolling resistance met the requirements of corresponding standards. |
